My husband and I hung some drywall on the ceiling (it was so heavy and difficult! My arms are still wobbly) last night. The problem is that we have a about a one and a half inch gap. Is there anything I can do to fix it? We cannot take the drywall down...is there something I can do besides that?
are you saying that you have a 1 1/2" gap from the new ceiling drywall to the wall drywall?? is this new drywall on top of bare ceiling joists?? the proper way to fix it is to take it down and reinstall.
not what you want to hear, but it is the right way.
If you have solid backing, then you can cut a small strip to fit into the gap. It won't be easy but it is possible. If you use a tapered edge, and cut the front and the back, scoring heavily, you can then nail or screw that piece into place.
Don't cut it to tight, because it will want to break easy. Then prefill gaps with mud and I would use paper tape for extra strength, not fiberglass.
If you don't have solid backing, you can take fiberglass tape and push it up into the gap but overlaping the sheetrock. Put just enough fast setting mud into the gap over the tape to hold it up, but not so much that it will sag out. Once that is dry, put another pass of fast setting mud in to try and bring that gap back to the surface of the sheetrock, but not so much to sag out again. Once the surfaces planes out with the sheetrock, then I would use paper tape to tape the seam not fiberglass.
